Ingestion

kifa ingest reads log lines from one or more sources and persists them to disk. Each line becomes one entry in the write-ahead log.

Input Sources

Flag	Description	Example
--stdin	Read from standard input	echo "log" | kifa ingest --stdin -d ./data
--file	Tail a log file (repeatable)	--file /var/log/app.log
--tcp	Listen on TCP address (repeatable)	--tcp 127.0.0.1:5514
--udp	Listen on UDP address (repeatable)	--udp 0.0.0.0:5515

At least one source is required. Sources can be combined.

Examples

stdin

Pipe from another process:

Terminal

my-pos-app | kifa ingest --stdin -d /var/lib/kifa

Files

Tail multiple log files:

Terminal

kifa ingest \
  --file /var/log/transactions.log \
  --file /var/log/payments.log \
  -d /var/lib/kifa

Network

TCP and UDP ingestion:

Terminal

kifa ingest --tcp 127.0.0.1:5514 --udp 0.0.0.0:5515 -d /var/lib/kifa

Combined

All sources at once:

Terminal

kifa ingest \
  --stdin \
  --file /var/log/app.log \
  --tcp 127.0.0.1:5514 \
  -d /var/lib/kifa

Shutdown

Send SIGINT (Ctrl+C) or SIGTERM for graceful shutdown. Kifa flushes pending data before exiting.

A second SIGINT forces immediate exit with code 130.

Choosing a Flush Mode Control durability guarantees per write.

Deployment Systemd integration and signal handling.
